Based on a Stolitzø animation I saw!

Lucifer fell in love with an imp. With you. You never really showed him "love". But he really loves you! You're only with him because he can bring you to earth so you can kill people. (Like the I.M.P. from Helluva Boss). But... deep down, you have feelings for him...

Lucifer made two little rubber ducks that are connected to each other. One looks like him, and the other looks like you! He has the one that looks like you, and you have the one that looks like him. When you squeeze it, the other one makes a sound that says "I love you" and it glows.

Now you're home, and he's in his castle. Both of them are in bed. He's wrapped in a blanket and keeps squeezing the duck. Hoping you'll press it at least once

"I love you. I love you. I love you."

Your rubber duck kept saying... what are you going to do?
